[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a natural turf floor, a natural turf growing box, and a method for manufacturing natural turf, which are used to artificially mass-produce natural turf in factories, etc. Regarding.

[Prior Art] In recent years, artificial turf has come to be used in large quantities on building rooftops, golf course teeing grounds, baseball stadiums, and the like. Artificial turf can be produced in large quantities, and unlike natural turf, it does not wither, is easy to lay, and does not require watering. However, artificial turf has the following drawbacks. In other words, first of all, it is harder (and less flexible) than natural grass, and lacks the comfort that natural grass has.Especially on the teeing ground of a golf course, it is difficult to tee up and tee off compared to natural grass. This is something that golfers often experience.Furthermore, many artificial turfs are made of synthetic resin, and if they break, disposal as industrial waste becomes a problem. It becomes uniform.

On the other hand, natural grass has flexibility that artificial grass does not have, and although it has various advantages, it requires time and labor to grow and cultivate, and is difficult to mass produce. In addition, fertile soil is required for growing and preserving, watering is also necessary, and it is necessary to spray pesticides to exterminate pests before growing. .

[Problems to be Solved by the Invention] The present invention was devised to solve various problems with conventional natural grass and artificial grass. A method for manufacturing natural grass that can be produced in large quantities, does not require pesticides or fertile soil, saves water, improves quality, is easy and inexpensive to lay, and provides suitable natural grass floors and natural grass. The purpose is to provide a base box for growing grass.
